GENERATO I HEATER.

Application filed sweat-e1- 11, was. Serial No. 147,757.

This invention relates to generator heat.- ers, such as the generators applied to or used in connection with oil burners.

In oil burner practice as l'ieretoforc followed, ithas been usual to spill a small quantity of oil beneath the gas generator and allow the oil to burn to thus Initially heat the generator. I This invention is designed to avoid the slow and uncertain process outlined above for initially heating the genirator, and objccts of such invention are to provide a novel form of heater for the generator oi an oil burner which is so eonstr'uctedthat lighted with a match as a gas stove is ligl'ited, for instance, and'which: will quickly heat the generator and permit the immediate use of the oil burner. 1

Further objects of this invention are to provide a very simple form of generator heater for oil burnerswhich of simple and practical construction, and which 13 reliable Figure 3 shows a further term oi: the in- 'cntion. a I

teferring to the drawings, it will be seen that the usual type of burner 1 has been illustrated, as provided with a mixing chamber .2 and an inlet nozzle 3 for the generated gas, such nozzle being: controlled by means of the hand Wheel 4', which latter con trols the valve rod 5. Above the burner, the transverse portion of the generator 6 extends, and is provided with a downwardly extending supply leg or pipe 7, which is ted through a pipe 8 from adjacent the bottom of the supplytank 9, such pipe being broken away in. Figure 1 tor the sake oi clcarness.

The other end oi? the generator extends downwardly, as indicated. at 10 and passes to the valve 10 and 'from thence to the nozzle 8.

The heater consists of a vertical pipe 11 provided with an air aperture 12 and with a centrally located upwardly directed nozzle This nozzle is supplied with under pressure through the pipe 141 in a manner which will he described,

A small tank 15 which may be of cylin- 'drieal form is provided, in addition to'the tank 9, and is partially filled with fuel, as indicated at 16. A central pipe 17 of small diameter extends downwardly through the fuel 16 to adjacent the lower end of the tank 15. This pipe communicatesthrough the "medium of the valve 18 with the upper portionof the supply tankfl and opens into the air space 19 of the supply tank. The supply tank may be "furnished with air under pres sure in any suitable or usual manners The upper portion of the tank 15 "communicates with the'pipe 14:, as shown in Figure 1.

In operating this apparatus, all that is i'iecessary is toopen the valve 18 and light the gas or combustible mixture at; the top of they pipe 11. This combustible mixture is furn shed from'thc compressed air in the portion 19 of the tank 9 which bubbles upwardly through the fuel in the tank 15 and" is saturated with the fuel. This saturated pressure gas flows upwardly through the nozzle 13 of the heater or burner 11 and entrains air and furnishes a combustible mixture which-is easily lighted, vasin an ordinary stove, forinstance. 1 l

'lhis-burner quickly initially heats the generator immediately adjacent the valve 10. Thereafter, the burner 1 may be very readily thrown into operation.

It will be seen that there is no necessity in the practice of this invention for spillinp a portion of the fuel. into a pan beneath the generatorininitiating the operation of the burner-, All that is necessary is to open the" valve 18 and light the heater with the same convenience as that experienced in lighting a gas burner. 7'

In the modified form of the invention shown in Figure 2, the same general principle is followed but a different type of carburct-ing apparatus is employed. In this form, the main supply tank 20 contains the :fuel 21 in the usual manner. The gas pipe the valve 23. A loosely formed wick 24 which may he of any shape, preferably cylindrical, fits within the pipe 21 at its up- "perend anddipsinto the fuel at its lower portly-n7 V a This pipe takes up the fuel by capillary 14 which passes to the heater for the burner. opens into an enlarged sleeve or pipe 21 pon at) action and carries it to the sleeve 21. The compressed air passing through the loosely knit or woven wick is saturated with the fuel and the rich gas passes through the pipe Ll. Y

In this form of the invention, the auxiliary earbureting tank or cylinder is avoided and, consequently, no additional tank is required.

Referring; to Figure 3, it willbe seen that the same inventive idea is carried out in a different manner in this form. The supply tank has a. pipe 26 communica ing with its upper portion and controlled by means of a valve 27. This pipe leads to a small nozzle 28 which is positioned within a. small sleeve 29. The sleeve is open at its outer end and is provided with apertures 30 adjacent its inner end. It is suln'nerged in gasoline carried within a tank 31, such tank being preferably provided with a lil ing cap From the upper portion of the tank a pipe 33 leads to the heater 34.. The heater may be of the same type as that previously described.

The operation of this apparatus is as follows:

The gas and air passing through the pipe 26 is projected as a violent blast from the nozzle 28 and entrains fuel, the fuel flowing inwardly through the openings 30, and being projected outwardly from the open end of the sleeve 29. This causes the formation of a multitude of very finely divided bubbles which, due to their intimate contact With the liquid and their relatively small size causes the air to become thoroughly saturated with the fuel. This saturated air passes to the burner which is used in the manner previously described. It has been found that this apparatus gives a very rich mixture and that it is easily operated and controlled.

Although the invention has been de scribed in considerable detail, such description is intended as illustrative rather than limiting the invention may be variously embodied and as the scope of such invention is to be determined as claimed.

e claim:

In an oil burner system, the combination of a supply tank adapted to contain fuel under air pressure, a burner supplied with fuel from said tank through a gas genorator, a heater for initially heating said generator, an auxiliary fuel supply tank adapted to contain fuel and having a pipe leading from its upper end and connected to said heater, a pipe leading from the compressed air space of the first mentioned fuel tank and extending to the lower portion of said. second mentioned fuel tank, said last named pipe opening into said tank through a nozzle, and a sleeve surrounding and spaced from said nozzle and having apertures adjacent said nozzles and an open end remote from said nozzle. a

In testimony that we claim tlfe foregoing we have hereunto set our hands at Milwaukee, in the county f Milwaukee and State of Visconsin.
